Abstract
The utility model discloses a transfusion-device with double-chamber dropper which comprises a dropper pot, a dropper and a filter which are arranged inside the dropper pot. Wherein the dropper is positioned at the center of the dropper pot and tightly connected with the inside wall of the dropper pot, and divided the inner chamber of the dropper pot into the upper chamber and the lower chamber for the compression chamber; the filter is arranged inside the upper chamber of the dropper pot. As adopting the technical design of the utility model, during the blood transfusion, to ensure no blocking of the filter screen to affect the flow, backwards and forwards pinch the around wall of the lower chamber of the dropper pot, the pressure of the lower chamber will push upwards to break up the accumulated blood coagulation matter and the foreign materials on the filter screen in the upper chamber; the filter will is smooth, the dropper speed and the blood purity can be ensured, so as to avoid the blood coagulation matter and the foreign materials going into the human body.
Description
Technical field
This utility model relates to a kind of medical apparatus and instruments, relates in particular to the double-cavity drop funnel on a kind of blood exchange transfusion set of being used for.
Background technology
Existing medical blood exchange transfusion set comprises needle for inserting bottle, flexible pipe, dropping funnel, flow regulator and venoclysis needle etc., needle for inserting bottle is by hose connection upper end to the dropping funnel kettle, the dropping funnel (see figure 1) is made up of dropping funnel kettle 1 and the dropper 2 and the filter 3 that are arranged in the dropping funnel kettle 1, dropping funnel kettle 1 is generally made with injection moulding or plastic uptake and expressing technique by PVC material, has certain elasticity; Dropper 2 is positioned at the upper end of dropping funnel kettle 1, and dropper 2 oozes 20 liquid of bleeding and is about 1ml; Filter 3 is positioned at the bottom of dropping funnel kettle 1, and it is blocked in the impurity in the blood on the filter and the energy blood clean.But, coagulation matters in the blood and impurity can be in the blood transfusion process blocking filter 3, influence transfusion speed even occlude blood and filter, the maneuver of taking usually in clinical is to pinch the perisporium of dropping funnel kettle 1 back and forth, to inflation in the dropping funnel kettle 1 its pressure is increased, to guarantee finishing smoothly of the process of transfusing blood.But because the construction features of existing dropping funnel, under the effect of squeeze pressure, this method but makes coagulation matters and impurity see through filter screen with blood easily and flows into human body, influence blood transfusion quality.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, and the double-cavity drop funnel on a kind of blood exchange transfusion set of being used for is provided, and it can be guaranteed blood quality and make finishing smoothly of blood transfusion process.
The purpose of this utility model is achieved by following technical scheme, a kind of double-cavity drop funnel that is used on the blood exchange transfusion set, comprise the dropping funnel kettle, be arranged on dropper and filter in the dropping funnel kettle, wherein, described dropper is positioned at the middle part of dropping funnel kettle and is connected with the inner wall sealing of dropping funnel kettle and dropping funnel kettle inner chamber is divided into epicoele and as the cavity of resorption of extrusion chamber, described filter is arranged in the epicoele of dropping funnel kettle.
The above-mentioned double-cavity drop funnel that is used on the blood exchange transfusion set, wherein, the epicoele of described dropping funnel kettle and the length ratio of cavity of resorption are 0.9～1.2: 1.
The above-mentioned double-cavity drop funnel that is used on the blood exchange transfusion set, wherein, described dropper is a funnel-form, it is to connect by hot pressing that its inner wall sealing with the dropping funnel kettle is connected.
The above-mentioned double-cavity drop funnel that is used on the blood exchange transfusion set, wherein, described filter is filtering screen or web plate.
Owing to adopted the technical solution of the utility model, in the blood transfusion process, influence flow for guaranteeing that filter screen does not get clogged, can pinch the perisporium of dropping funnel kettle cavity of resorption back and forth, the pressure of dropping funnel kettle cavity of resorption is upwards pushed away, the coagulation matters and the impurity that are deposited on the filter will be broken up by intracavity on the dropping funnel kettle, make filter unimpeded, thereby guarantee dropper amount of dripping and blood cleanliness factor, make coagulation matters and impurity can not flow into human body.
Description of drawings
Fig. 1 is the structural representation that is used for the dropping funnel on the blood exchange transfusion set of prior art;
Fig. 2 is the structural representation of the double-cavity drop funnel on the blood exchange transfusion set of being used for of the present utility model.
The specific embodiment
See also Fig. 2, double-cavity drop funnel on the blood exchange transfusion set of being used for of the present utility model comprises dropping funnel kettle 1, dropper 2 and filter 3, wherein, dropping funnel kettle 1 is generally made with injection moulding or plastic uptake and expressing technique by PVC material, dropper 2 is positioned at the middle part of dropping funnel kettle 1 and is connected with the inner wall sealing of dropping funnel kettle 1 and dropping funnel kettle 1 inner chamber is divided into epicoele 11 and cavity of resorption 12, cavity of resorption 12 is as extrusion chamber, the epicoele 11 of dropping funnel kettle 1 is 0.9～1.2: 1 with the length ratio of cavity of resorption 12, dropper 2 preferably is positioned at the length center of dropping funnel kettle 1, this dropper 2 is a funnel-form, and it is to connect by hot pressing that its inner wall sealing with dropping funnel kettle 1 is connected.
Described filter 3 is arranged in the epicoele 11 of dropping funnel kettle 1, and it can be filtering screen or web plate.
Owing to adopted the technical solution of the utility model, in the blood transfusion process, for guaranteeing that filter screen does not get clogged and dropper 32 oozes 20 liquid of bleeding and is about the flow of 1ml, can pinch the perisporium of dropping funnel kettle cavity of resorption 12 back and forth, the pressure of dropping funnel kettle cavity of resorption 12 is upwards pushed away, the coagulation matters and the impurity that are deposited on the filter 3 will be broken up in the epicoele 11 of dropping funnel kettle 1, make filter 3 unimpeded, thereby guarantee 2 amounts of dropper and blood cleanliness factor, make coagulation matters and impurity can not flow into human body.
Above embodiment is only for the usefulness that this utility model is described, but not to restriction of the present utility model, person skilled in the relevant technique, under the situation that does not break away from spirit and scope of the present utility model, can also make various conversion or modification, therefore all technical schemes that are equal to also should belong to category of the present utility model, should be limited by each claim.
